Daily Checklist
A daily inspection of the water heater cabinet should be performed with attention paid to the
following:
Check for Strong Odor of Gas
•
If a leak or the odor of fuel is noticed, immediately turn off all power switches and
the main fuel supply to the water heater cabinet.
•
Ventilate the water heater cabinet.
•
Find and correct the leak before turning on any power or trying to relight the water
heater.
Check Heat Transfer Fluid “HTF” Level Everyday
•
Maintain between ¼ and ¾ on the heat transfer level gauge when fluid is hot.
•
Top up as necessary.
•
For “HTF” specification, see “Setup, Heat Transfer Fluid, “HTF”, Fluid
Specification.
•
For “HTF” handling precautions, refer to “Safety Concerns, Material Safety Data
Sheet”.
•
If loss of fluid is excessive, check for leaks at all the fittings and connections in the
water heater cabinet as well as the fluid circulation system.
Check the Supply Temperature Gauge
•
Verify that the supply temperature gauge is within 10 F of the aquastat setting.
Seasonal Checklist
Fuel (water block/particulate) filter
•
The water block/particulate filter should be changed every heating season or as
required.
Hoses
•
Periodically check all hoses for damage due to aging, elevated temperatures, over-
torqued hose clamps, abrasion and weathering.
•
Replace damaged hoses as required.
•
Seasonally check hose clamp torque and adjust accordingly.
Water Heater Heat Exchanger
•
Keep the flues in the water heater clean. Because soot is a nonconductor of heat, a
dirty water heater requires more oil to heat a structure than a clean one. Water
heaters can corrode on the fireside. This results from corrosive substances in the fuel
